This is the classic floating thermometer for a pool or spa, with a cheerful animal head as the float. The clear tube with the scale hangs below it in the water; the figure keeps the whole thing upright, so you can read it from the edge.
Kokido makes this thermometer in three versions - a yellow duck, a green turtle and a blue dolphin - and ships them mixed. So you do not pick the model yourself: you receive one thermometer, in one of the three figures.
The scale runs in degrees Celsius and in Fahrenheit. No battery is needed. A cord on the thermometer lets you tie it to the ladder or the rim, so it does not drift off to the middle of the pool.
Handy with an above-ground pool in the garden, where the water temperature differs from day to day: children usually go and check for themselves how warm it is before they jump in.
